Cervical cancer is the second most common cancer causing death in women. The most important risk factor for the development of cervical cancer is genital infection with human papilloma virus (HPV). Human papillomavirus (HPV) is the most commonly sexually transmitted infection, and there are more than 100 known HPV types, the majority of which are not harmful. About 75% of HPVs have been associated with non-cancerous warts (papillomas) on the hands, chest, arms and feet, such as low-risk HPV types 6 and 11. Testing for the most prevalent high risk types, is an important criteria in the prevention of cervical cancer.
